Antunes Controls 803113301 Pressure Switch

The Antunes Controls 803113301 is a job-ready RLGP-H low gas pressure switch designed for critical monitoring in commercial and industrial combustion systems. This automatic reset pressure switch features a sensing range of 1-7 PSI, making it a staple for maintaining safety in gas trains and burner manifolds. Built with a rugged die-cast aluminum housing, the Model H gas pressure switch is engineered to withstand the demanding environments of a mechanical room while providing precise repeatability. The SPDT electrical configuration allows for seamless integration into 120-250 VAC control circuits, breaking the circuit when pressure drops below your specific set point. With a standard 1/4" NPT connection and a 1/8" NPT vent, this unit offers a straightforward drop-in replacement or new installation. Contractors trust this UL/FM/CSA approved device for its reliability and its ability to be mounted horizontally without the need for specialized leveling, ensuring high performance in diverse HVACR applications.

Key Benefits for Contractors

• Broad Compatibility: The 1-7 PSI adjustable range and 1/4" NPT gas inlet make it compatible with a wide variety of industrial gas-fired equipment.
• Resilient Construction: The die-cast aluminum base and durable enclosure provide long-term protection against the rigors of high-temperature boiler rooms (up to 140°F).
• Automatic Reset Logic: The auto reset function ensures the system resumes operation immediately once safe pressure levels are restored, reducing unnecessary service calls for manual resets.
• Visible Diagnostics: Includes a clear ON-OFF indicator, allowing technicians to verify switch status at a glance during routine maintenance.
• Safety Certified: Fully compliant with UL, FM, and CSA standards for industrial gas monitoring and combustion safety.

Common Questions

What is the maximum surge pressure for the 803113301?
This model is rated for a maximum surge pressure of 35 PSI, ensuring the internal diaphragm is protected against moderate pressure spikes in the gas line.

Can the RLGP-H model be mounted in any orientation?
Yes, the 803113301 can be mounted horizontally without the need for precise leveling, though upright vertical mounting is generally preferred for optimal longevity.

Is the 803113301 suitable for high-pressure gas applications?
This is a low gas pressure switch specifically designed for 1-7 PSI ranges. If your application requires high-limit monitoring above 7 PSI, you should look at the RHGP-H series or the 6-15 PSI variants.
